Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few ...

Abstract: Near-Field Communication (NFC) has enabled mobile devices to emulate contactless smart cards, which has also rendered them susceptible to relay attacks. Numerous countermeasures have been ...

Abstract: Angular displacement sensors often face a trade-off among high measurement accuracy, low environmental sensitivity, and an ultra-large hollow structure. This paper presents an large size ...
